Qualification Pedigree

2-V to 6-V V_CCOperation

Inputs Accept Voltages to 6 V

Max t_pdof 7.5 ns at 5 V

(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

DESCRIPTION

This octal buffer and line driver is designed specifically to improve the performance and density of 3-state

memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The SN74AC244-EP device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs.

When OE is low, the device passes noninverted data from the A inputs to the Y outputs. When OE is high, the

outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CCthrough a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
